What temperature is used when calibrating a thermometer with crushed ice and water?

1. 0 degrees F

2. 32 degrees F

3. 50 degrees F

4. 68 degrees F

The correct answer is: 32 degrees F

When calibrating a thermometer with crushed ice and water, the appropriate temperature to use is 32 degrees Fahrenheit. This is because the freezing point of water is defined as 32 degrees Fahrenheit (0 degrees Celsius). Using a mixture of crushed ice and water creates a stable environment that accurately reflects this temperature, making it an ideal reference point for calibration. Calibration is essential for ensuring that a thermometer provides accurate readings, which is crucial in food safety and preparation. By adjusting the thermometer to read 32 degrees Fahrenheit in this calibration method, you can ensure that it will provide reliable measurements when used in various cooking and food storage scenarios. The other temperature options do not correspond to the freezing point of water, and thus would not provide a suitable baseline for calibrating the thermometer.
